kvmppc_mmu_map – create a host mapping for guest memory

If the guest wanted a larger page than the host supports, only the first host page is mapped here and the rest are demand faulted.

If the guest wanted a smaller page than the host page size, we map only the guest-size page (i.e. not a full host page mapping).

Caller must ensure that the specified guest TLB entry is safe to insert into the shadow TLB.
